The Bar chart from the front page

This is the Bar chart from the front page of the website (as of 10th September 2012).

[No canvas support]

This goes in the documents header:
<script src="RGraph.common.core.js"></script>
<script src="RGraph.common.effects.js"></script>
<script src="RGraph.common.tooltips.js"></script>
<script src="RGraph.common.dynamic.js"></script>
<script src="RGraph.bar.js"></script>
Put this where you want the chart to show up:
<canvas id="cvs" width="600" height="250">
    [No canvas support]
</canvas>
This is the code that generates the chart:
<script>
    window.onload = function ()
    {
        var bar = new RGraph.Bar({
            id: 'cvs',
            data: [[45,60],[65,30],[40,80],[62,48]],
            options: {
                labels: ['Luis', 'Kevin', 'John', 'Gregory'],
                tooltips: ['Luis','Luis','Kevin','Kevin','John','John','Gregory','Gregory'],

                backgroundGridAutofitNumhlines: 5,
                backgroundGridAutofitNumvlines: 4
            }
        }).fadeIn({'duration': 250});
    };
